How reflective film is laid in the bath. Overview of vapor barrier materials for the bath. What materials are used in different rooms of the bath

Vapor barrier is necessary for the bath to protect the walls, floor, and especially the ceiling from excessive exposure to moisture. It serves as a barrier to evaporated moisture and prevents it from penetrating into the structure itself, thereby protecting it from destruction. It should be noted that the vapor barrier layer and waterproofing are not the same thing at all. The first protects the building from the inside, the second - from the outside. In this case, different materials are used, the configuration of their installation is also different.

Most of all, the walls and ceilings in the steam room and washing room require a vapor barrier layer. The floors need more waterproofing. The main function of the vapor barrier material is the safety of the insulation, which is laid between the lining and the heat insulator. The latter is quite hygroscopic and is able to quickly absorb moisture, which destroys all elements of the finish and violates the insulation.

The vapor barrier ball serves to neutralize changes in humidity, the negative effects of climate with sudden changes in temperature and help protect the bath from condensation.

Vapor barrier for ceiling

A vapor barrier is installed for the bath, starting from the ceiling and further down the walls to the floor. Hot air always rises, so protecting the roof from steam loss is the main task. For a bath from a bar suitable trim blocks or thin boards. The latter will need a lot. Next, you need a cardboard, foil layer or wax paper. The material is impregnated with drying oil, left to dry completely and then insulated.

You can also use the following combination: unedged board at least 5 cm thick, with which the ceiling beams are sheathed, a board of the same thickness is fixed in a configuration - across. Linden is the most suitable here. After, everything is sealed with cardboard with drying oil and plastered with clay (or polystyrene plates), on which the insulation is laid. It is more profitable to install plates, since they do not exfoliate over time and take a minimum of installation time.

Bath wall vapor barrier

It is necessary to use polyethylene film, parchment or aluminum foil. Roofing felt and roofing felt cannot be used in the steam room, they evaporate when heated bad smell and release toxins. For the walls of the steam room the best option- foil vapor barrier.

In the washing and steam rooms, polyethylene with a thickness of 14 cm can be used. The walls of the rest room are finished with kraft paper. An approximate diagram of the order of work in the photo below.

Which thermal insulation layer to choose

What vapor barrier layer is needed for the floor? One of the most effective is stizol. It is distinguished from self-adhesive material by a longer installation stage. You can make a clay puff with clay mixtures (peat and perlite) and subsequent coating with foil or polyethylene.

But still, steezol can withstand high thermal loads, and for a steam room this is the best option. It will help save on heating, keep the required temperature for a long time and will not suffer from humidity.

For modern baths Increasingly, polypropylene balls are used as a vapor barrier. They can reflect heat rays, isolate steam and retain heat at the same time. The advantages of polypropylene include:

• temperature regime + 50-150. FROM;
• additional noise-absorbing and heat-insulating qualities;
• lungs installation work: you only need a stapler, knife, nails and adhesive tape;
• not susceptible to rotting or corrosion;
• complete environmental friendliness.

Innovation in vapor barrier - isospan. This is a foil-based material with the addition of a kraft paper layer. It perfectly protects wooden structures from internal steam and moisture. It is used for rest rooms and locker rooms.

So, for the ceiling in the bath best layer vapor barrier - polystyrene boards(Izospan, Penoplex, etc.). For floors - foil film, and for walls - isospan and foil.

The vapor barrier is laid in order, since a violation of the technology for placing gaskets in the design of the bath will lead to its rapid wear and destruction.

The vapor barrier layer should not only retain heat and stable humidity in the steam room, but also protect the walls from the effects of that same humidity. For the most budget option you can choose the slag, wood chips or sawdust, peat, pressed straw. The main thing is for what period of operation the owners will expect.

If the building will be used as a Russian bath, and not a sauna, the ceilings and walls of the steam room cannot be protected with unsuitable materials. The roofing should be covered with overlapping paper and fixed with 5x5 cm bars. The foil should be completely monolithic and fixed with aluminum adhesive tape.

Choosing a high-quality adhesive tape is not difficult: immediately upon purchase, check for strength, for which glue it to the foil and try to tear it off. FROM ordinary tape this number will not work.

Also, do not forget about the functionality of the extreme sections and joints, which will be a deterrent for heat and steam loss. This is what will ensure the tightness of the room for the steam room. Especially on the ceiling.

Baths from the frame require vapor barrier in without fail, but the log cabins and log buildings can do without it. For best effect you can use mineral wool as a heater, up to 15 cm thick. Log baths are already sewn into boards, the thickness of which is not less than 6 cm.

When building a bath, one of important criteria assessment of the quality of construction is the ability of the bathhouse to retain heat. Therefore, the main task is to create the well-known “thermos effect” in the bathhouse.

The bath should always guarantee stable high temperature indoors. This is not easy, since baths built of brick conduct heat well, but that is why they cool quickly, and wooden ones rot from moisture over time. Therefore, holding quality warmth and vapor barrier in the bath still at the construction stage - one of the main conditions for maintaining optimal temperature regime, which will allow you in the future not only to feel comfortable, but also to properly heal your body.

The vapor barrier of a bath is a created vapor barrier, in most cases it is a vapor-tight film that protects walls and roofs from water vapor. Such a barrier does not allow moisture that is in the air to pass through.

The vapor barrier of the bath helps to extend its service life, while eliminating negative factors even at the construction stage. These factors include:

• climate features
• seismological hazard
• aggressive environment

In order to carry out the vapor barrier of the bath, it is not necessary to invite specialists, you can do it yourself. In the construction market, you can choose materials that correspond to the allocated budget and the task assigned to the owner of the bath.

Building materials for vapor barrier baths can also serve as energy saving material. With the correct development of an engineering project, it is possible to increase the ability to keep heat inside the room and avoid condensation. In addition, the materials must be protected from wind and penetration into the bath of cold air from outside.

Starting to mount the vapor barrier in the bath is from the ceiling, smoothly moving to the walls and the door.

Bath ceiling vapor barrier

Hot steam always rises to the ceiling, so first of all, you should take care that steam does not leak through the roof. If the bath is made of log beams, then the ceiling is sewn up with chopping blocks, thin boards can also be used, but they will need a lot more.

A layer of vapor barrier material is sewn over the boards. For this purpose, you can use thick cardboard, foil or waxed paper soaked in drying oil. Sheathed ceiling is covered with a layer of clay, left to dry. After the treated ceiling should be insulated.

If you still doubt whether to carry out insulation work in the bath? Find out and your doubts will disappear.

Technological progress offers us different kinds vapor barrier for the ceiling. Check out the most effective and inexpensive materials.

There is another way to vapor barrier the ceiling. On the ceiling beams sewn on edged boards, about 5 centimeters thick, across them there are still boards of the same volume. For this purpose, lime lining is often used, because this material is affordable and meets the requirements. Then the boards are covered with a layer of cardboard impregnated with drying oil, plastered with clay. Insulation is laid on a layer of clay.

Instead of clay, you can use polystyrene plates. They are easier to install, do not peel off, and the workflow takes much less time than in the case of clay. Such a vapor barrier of the ceiling is important in the steam room itself, in other rooms the ceiling can be decorated with one clapboard.

Bath wall vapor barrier

As soon as the work on the ceiling is completed, you can proceed to the vapor barrier of the walls of the bath. Material for work is selected only after a plan for waterproofing, thermal insulation and vapor barrier is drawn up. If at this stage you miss some trifle, in this case you will not achieve your main goal - to save heat in the room.

To avoid condensation, polyethylene film, glassine or aluminum foil is used to decorate the walls.

In the steam room it is not recommended to use roofing felt and roofing felt. Because during operation they emit toxic substances that have an unpleasant odor and are harmful to health. To decorate the walls in the steam room, it is better to choose a foil that copes with the task and is safe for health.

Often, a polyethylene film with a thickness of no more than 140 millimeters is used to decorate the washing room and steam room. As for the locker room and recreation areas, the walls can be decorated with kraft paper.

As an economical option for vapor barrier of the walls of the bath, you can use rolled fiberglass or foil. These materials have a similar structure, fit perfectly and are affordable.

As soon as the installation of the vapor barrier of the walls is completed, it is possible to start sealing the joints. This is done with aluminum foil and tape to completely eliminate the possibility of drafts.

The vapor barrier of the walls of the bath is hidden, as it were, inside the wall, and only aspen or linden boards remain not on the surface. The interior of the bath looks attractive, and at the same time preserves it. healing properties, extending the service life.

Bath insulation materials

Based on the fact that the installation of heat and vapor barrier is aimed at avoiding the occurrence of condensate, different materials can be used for this. The cheapest and most popular option is a mixture of clay and sawdust. It applies beautifully, dries quickly and almost does not crumble.

You can also use a clay screed backfill with a mixture of perlite and peat, and then cover it all with foil or polyethylene.

Stizol is considered one of the best options for vapor barrier baths, common view or self-adhesive. The properties of these two types of material are identical, the only difference is that with self-adhesive material easier to work.

In addition to vapor barrier, stizol helps to preserve heat in the room, so such a purchase is beneficial from an economic point of view. This material is able to withstand severe thermal loads, therefore perfect option for a couple. It is also resistant to humidity and temperature changes. Thanks to styzol, the bath room heats up quickly and saves for a long time. optimal temperature, heat loss while being insignificant.

Today, vapor barrier films such as Isoltex and Armitex are becoming increasingly popular. The Armitex film is placed inside the bath, under the casing, and Izoltex is placed on top of the thermal insulation, outside the bath.

For the vapor barrier of the bath, you can also use materials laminated with foil. For example, foamed polypropylene Penoterm NPP LF. It perfectly reflects heat rays, keeping them indoors, and at the same time perfectly performs the function of insulating steam. Back to main features this material should include:

• application temperature from -50 to +150 degrees
• powerful thermal insulation, vapor barrier and sound insulation properties
• ease of installation (easily cut with a knife, mounted with a furniture stapler, small nails, can be glued with adhesive tape)
• not subject to corrosion, decay
• environmental friendliness

Izospan (for example, Izospan FB) is a foil material based on kraft paper, which is also used to insulate baths, saunas and other wooden structures from steam and moisture. An example of mounting Izospan, see this video:

The cost of various materials for vapor barrier baths and saunas:

Lounges and locker rooms can be decorated with kraft paper. It is breathable, durable, easy to install and has a presentable appearance. appearance. Kraft paper is one of the types of material that combines the best option for cost and quality.

It should be noted that the more combined materials you choose to work with, the more effective the result will be.

Having drawn up a plan for vapor barrier, warming the bath and choosing the right materials for work, you can perform two tasks at once: ensure long term service and efficiency of the bath, as well as save your budget. A serious approach to business and a little diligence will allow you to build a bath that will bring you and your dear people pleasure for many years.

A bathhouse is a place where heat and steam rule. But this whole system works only with the proper level of vapor and thermal insulation. How to install a vapor barrier in a bath on your own, you will learn about it below.

Why do you need a vapor barrier in the bath?

Vapor barrier is not only a barrier that prevents steam from escaping and spoiling the whole essence of the work of a steam room, it is also reliable protection from reducing the life of the bath, because steam and water affect the walls and other components of the building, reducing its durability. By solving the issue of vapor barrier at the construction stage, you will save your bath from such problems.

We make a vapor barrier of the ceiling in the bath with our own hands

Steam rises to the ceiling. This is an immutable law of physics. Therefore, thinking how to install vapor barrier in bath, first of all, you should think about the ceiling. It's just the lack of vapor barrier top floor leads to the loss of approximately 30% of all heat.

The ceiling in the bath should be protected with boards at least 6 cm thick. Aluminum foil and paved paper impregnated with drying oil should be laid on top of them. A clay layer is placed on top and a layer of insulation is spread. This is one of effective options bath ceiling vapor barrier.

An important point: reliable vapor barrier in the bath is needed only in the steam room. In the rest of the rooms - washing, dressing room, vestibule, if any, there is enough lining attached to draft ceiling. The wood itself, to one degree or another, has the properties of a vapor barrier.

Vapor barrier of the walls in the bath

For this purpose, the most different materials, including aluminum foil, roofing felt, plain film, roofing felt and glassine. Although it is better not to use the last two and roofing material - you can get a bath with not the most pleasant smells, and when heated, these materials can release harmful substances.

The vapor barrier of the walls protects the insulation from condensate and gives the room the so-called "thermos effect". You can use Armitex and Izoltex films, and also among large selection modern materials can be found and those that play the role of a vapor barrier and insulation at the same time.

Separately, it is worth highlighting materials with foil lamination. They reflect heat radiation, help melt the bath and keep the temperature in the rooms at the right level.

Please note: if you decide to use conventional insulation for insulation polyethylene film, be sure to leave a gap for condensate to evaporate. If this is not done, you can get a greenhouse effect, in fact, that is why such a film is not the most popular material for vapor barrier. It is better to use a special film with villi that hold condensate.

Now you know, how to install vapor barrier in a bathroom. This is very important point, since the bath is a structure with special standards of operation. The formation of a microclimate will depend on the vapor barrier device, and therefore the health benefits or harms of staying in such a steam room.

A Russian bath on a personal plot is a real wellness complex at home. Putting wooden frame, the masters strive to do everything with high quality, “for centuries”, and the vapor barrier for the bath plays a decisive role here. Hot water vapor, which is so important in bathing procedures, can destroy thermal insulation and lead to drying out of log walls. To prevent this from happening to your building, we will review the materials for the vapor barrier of the Russian bath and consider the basics of their installation.

The vapor barrier in the bath experiences a temperature load. In the dressing room and washing part, it is not critical, but in the steam room, where heating can exceed 100 ° C, many synthetic materials begin to melt and release harmful substances. For this reason, the scope of cheap polyethylene film, roofing felt, roofing material, glassine is limited by room temperature. Expanded polypropylene products are often less heat resistant than specified by the manufacturer.

1. A traditional solution of clay with sawdust remains a reliable and environmentally friendly vapor barrier. But technology requires a lot of time, effort, and raw materials are not always at hand.

2. For warming log cabin or stone walls baths are suitable for materials of natural or synthetic origin, but they can also deteriorate from dampness or release toxic substances when heated strongly.

3. Glass wool is the wrong option. Over time, it begins to release harmful substances, poisoning the microclimate in the bath.

4. Extremely durable and safe product is aluminum foil. It is used in the latest vapor barrier films, providing up to 90% energy saving, and is used in baths, saunas and hot shops in production. Vapor barrier can extend the life of the insulation up to 50 years.

The sheets are glued with an overlap, fixing the joints with heat-stable adhesive tape. The installation scheme of the vapor barrier on the ceiling and walls of the bath provides for an obligatory air gap between it and the sheathing panels. With properly executed thermal and vapor barrier in the bath, the “thermos effect” is achieved, the room heats up quickly and keeps heat for a long time. The latest species insulation for baths and saunas combine the properties of a vapor barrier and a heater, withstand high temperatures, are easy to fit, and have a minimum thickness.

Reflective vapor barrier for baths Izospan - one of best products modern market. This material consists aluminum foil, reinforced with lavsan threads, and kraft paper, is produced in rolls of 35 m. It is able to save original shape under conditions of temperature difference, does not emit any harmful substances, is an absolute reflective vapor barrier.

Independent vapor barrier of the bath room

The steam moves up and to the sides, which means that the ceiling and walls are more affected by it. However, with poor-quality vapor barrier, it can rush into any loophole, causing damage to the material and freezing. Without waterproofing the floor in the washroom, all insulation measures will not be enough. When the floor is sealed and the walls are insulated, they start laying the vapor barrier in the sauna or bath.

Vapor barrier and insulation of the bath ceiling protects it from maximum thermal loss. There are two variants of the insulating "pie":

• The surface is sewn up with a board or a die from 5 cm thick.
• From above (outside the room) a vapor barrier is mounted.
• A layer of clay 1-2 cm is applied and mineral insulation is laid (foam glass, expanded clay, mineral wool, etc.).
• A boardwalk or a cement-sand screed is made on top.

Particular attention should be paid to the vapor barrier in the steam room, where the temperature under the ceiling is maximum. Even with thick sheathing, plastic film can melt and impregnated materials begin to release toxic or strong-smelling substances. It is better to use hardwood lining, for example, aspen. Resin protrudes and drips from the needles when heated. A quality product made of expanded polypropylene is able to withstand +100 °C, film foil insulation - up to +140 °C.

The second option provides for an air gap:

• From a tongue-and-groove board 2-3 cm thick finishing panel and is mounted on thick beams with a section of 20 x 20 cm.
• Boards are twice rubbed with drying oil for water resistance.
• Over the beams, transverse boards of the crate are stuffed.
• The vapor barrier is laid with foil inside the room and fixed with mounting rails. Joints are sealed with aluminum tape.
• Sand, slag or specialized insulation is poured on top.

Sawdust and other combustible materials should not be used for the ceiling of the steam room - this threatens to ignite spontaneously. The earth cannot be used either, it contains many microorganisms and will infect the building with mold. Do not forget about ventilation - the accumulation of carbon dioxide and carbon monoxide leads to poisoning of people. Provide reliable vents in all areas of the bath.

Save money with reflective film

Installation of foil vapor barrier on the walls of the bath also requires an air gap. If it comes into contact with a sheathing or other surface, heat is conducted by aluminum, like any metal. This rule is in response to frequently asked question home craftsmen: which side to lay the vapor barrier? Obviously, you need to reflect the heat inward, and not the cold outward. At correct use This option pays for its cost twice.

If you want to save money by choosing cheap materials for the dressing room and washing room, remember that the service life of polyethylene is very short. First of all, it cracks on the folds left from the factory packaging. They should be reinforced with adhesive tape when installing the vapor barrier. If the film has lost its tightness, the insulation will begin to dampen, so it is better to use hydrophobic products in advance. It will be more profitable to buy a vapor barrier for Isospan baths due to its exceptional durability and unique properties.

Foil vapor barrier Izospan FB is designed specifically for rooms with elevated temperatures. Her specifications allow you to lay the film directly on the wall without additional thermal insulation. The rolled web is stretched in transverse strips and fixed with vertical slats. The sheets are mounted from the bottom up, overlapping, with a margin of 15 cm and the joints are glued with heat-resistant aluminum tape. A wooden crate for sheathing is stuffed over the vapor barrier. The gap between it and the foil should be at least 4-5 cm.

The price of vapor barrier Izospan FВ reflecting 35 m 2 will be only 18.5 rubles. A width of 1.2 meters makes it easy to calculate the required amount of material, taking into account stocks for joints. The cost per roll at the manufacturer's price is 775 rubles.

Warm moist steam is the basis of the microclimate in the bath, which contributes to the greatest comfort in taking hygiene procedures. But its properties are different from ordinary air. room temperature including density and pressure.

Properly equipped vapor barrier in the bath – part of the wall and ceiling insulation. The durability of this specific structure largely depends on it, no matter what building materials a bathhouse, steam room or sauna is built from.

Steam is detrimental to many building materials, including metal, untreated wood, especially during cooling, when condensation forms on the surface. Any building, residential or auxiliary, involves a multilayer arrangement of the surface of the floor, walls and ceiling. This is necessary to ensure:

• insulation;
• waterproofing;
• energy saving;
• long-term and flawless operation of the building.

A vapor barrier is not only a protective membrane or foil vapor barrier for a bath. This is a whole range of measures, including the processing of building materials, the tightness of the joints, the protection of the insulation from water penetration.

Moisture that got into basalt wool, ecowool or other porous material, it is difficult to get out of there. It reduces thermal insulation properties, especially in severe frosts, when it becomes ice. Excessive humidity without air circulation - favorable environment for putrefactive and pathogenic bacteria, mold and fungus development.

The set of measures also includes natural and forced ventilation, providing a decrease in air humidity with an influx of oxygen at the end of water and hygiene procedures.

Steam is dangerous because hot moisture quickly penetrates building materials and settles in insulating layer. The settling condensate leads to the gradual destruction of the surfaces. Its pressure is higher than the standard - atmospheric, and this negatively affects the structures and finishing materials. When cooled, a dew point is formed when the steam becomes water and condenses out, destroying metal (corrosion) and wood. Materials with high vapor permeability "breathe", that is, they absorb excess moisture, then give it away when the air humidity decreases.

Part of the latest generation is produced multi-layered, with an energy-saving layer, in order to make them more economical with thoughtful construction of baths. A competent vapor barrier device for a sauna or steam room increases efficiency heating appliances significantly reduces power loss.

Multilayer and membrane materials provide optimal microclimate when organizing thermal insulation for a bath. They also have other properties - additional waterproofing and wind protection.

The most common materials for bath vapor barrier

Modern vapor barrier technology for a bath is performed both by "old-fashioned" methods, and by the latest technologies. This is facilitated by the appearance of high-tech materials on the building materials market, the addition of new layers to the "classic" heat and vapor barrier. For example, reflective insulation in the form of aluminum foil or "breathing" impregnated glassine.

The construction market is replete with offers in the niche of materials for arranging vapor barrier. Among them, Isospan, Armiteks, Penoplex are gaining popularity. Ordinary polyethylene film is being replaced with specialized membranes, but obsolete roofing felt and roofing material are still used in summer cottage construction.

It is undesirable to use such old-style materials in a steam bath - they contain resins that emit formaldehyde when heated with steam. And it is preferable to use glassine only because of the minimal ability to reflect moisture from the surface of the walls.

Companies involved in the construction of san and other structures of similar functionality do not save on materials. At self-build country baths have to choose practical and available materials. Primary requirements:

• resistance to the combustion process;
• environmental friendliness;
• reliability in operation;
• resistance to rotting and decomposition;
• heat resistance;
• moisture resistance.

Clay or a mixture of oily clay with sawdust is used less and less today, but this is the most affordable, proven over the years, eco-material. Although the sawdust itself is combustible, it makes the coating mixture more resistant to cracking. For walls, a layer of 2 cm is sufficient. The main property of clay is that it “breathes”, that is, it absorbs excess moisture, and then gives it away when it dries. And the heat only makes it harder.

Temples were even built on this property in Vietnam - they smeared bales of straw on the outside with clay and burned them on the inside. These temples are still standing today.

foil materials

Aluminum foil is used for sheathing unprotected surfaces and porous thermal insulation. Known for its maximum ability to reflect heat into the steam room and repel moisture from the surface of the walls. It does not react to high temperatures, does not have toxic fumes, does not deform, and is resistant to mechanical stress.

Like any metal, the foil forms condensation when it cools sharply, so it is not recommended to open the doors abruptly in frosty weather with excessive humidity. If this is a multilayer vapor barrier system for a steam room, and the room itself is with sufficient insulation and air conditioning, then these manifestations should not be.

Foil material gives the best insulating performance in combination with full-fledged multi-layer insulation and an air gap between it and the reflective layer. Insulation with sheets of aluminum foil is overlapped, the lower edge is brought out to the floor, and the joints are treated with special adhesive tape for foil insulation.

The latest generation of 3-in-1 multi-layer materials used for complete insulation are often provided with a foil coating. They combine several functions:

• thermal protection;
• vapor barrier;
• the ability to reflect heat into the room (does not transmit thermal and infrared radiation).

Film materials

Film vapor barrier or protective membrane is quite reliable. Like any other film, it makes a deceptive impression, but it is tear-resistant and not subject to deformation during operation. With it, it is easy to protect multilayer insulation from warm steam.

It is used indoors over porous materials, covering the surface of an insulated ceiling or walls. But if the joints of the membrane are not tightly connected or make a hole during installation, then its vapor barrier properties will be minimized.

The easiest way is to attach the film to the slats of the wooden lathing of the ceiling over the mineral wool (another insulation between the beams) with brackets construction stapler. The canvases are not pulled very tightly, leaving minimal sagging, the sides of the membrane are overlapped. The seams of the film strips are fixed with special adhesive tape.

Membrane materials

The most reliable vapor barrier membrane is multilayer with mesh reinforcement. Reinforcement protects film materials from deformation under temperature changes, so such membranes are the most durable.

Do not stretch membrane materials so that they can respond to temperature fluctuations by expanding or slightly. From a heavy load, with improper installation and a large temperature range, it gradually loses its elasticity - let it sag slightly between the rails.

Modern materials

• Kraft paper is a kind of technical cardboard widely used in construction. The vapor barrier coefficient is much lower than that of the membrane, but the material "breathes". It is recommended to use baths for auxiliary premises - a dressing room, a dressing room, a rest room. Excess moisture destroys it, like any cardboard.

• Penotherm is considered a high-tech heat and vapor barrier material that has proven itself in steam rooms. Produced in the form of foam boards with a protective layer, it perfectly tolerates high levels of humidity and temperature.

• Among the materials of the new generation, used simultaneously as a thermal barrier and vapor barrier of the bath, experts single out penofol and related commodity items. It's multilayer roll materials based on foamed polymers. The foil-protected polypropylene layer has good thermal insulation.

Such materials protect the walls from the penetration of steam, reflect infrared and thermal radiation during interior, therefore, make the bath more economical when heating and maintaining the required temperature. They prevent the formation of condensate in the thermal insulation layers, serve for a long time and flawlessly. The material works great in a sauna or steam room, but you should not overheat above +100°C, so as not to destroy the inner layer.

Although manufacturers write high temperature limits, this refers to a short-term one-time amplitude jump. From constant overheating, any foamed polymer begins to compact, decompose into toxic components, melt or gradually char. For the body, a record temperature is a great stress for survival, a colossal load on the brain, heart and blood vessels!

Izospan is also recommended by experts in the construction of baths as one of the best offers on the construction market. It is produced in rolls of 35m, which contain a protective layer of aluminum foil and reinforced insulation. The material does not emit toxic substances when overheated, does not deform and is considered an excellent vapor barrier, easy to install and reliable in use.

Two-layer roll material, from the inside - rough layer to collect condensate, after normalizing the humidity in the bath, it evaporates it. It is reliable in operation, has high protective characteristics when arranging vapor barrier from inside the premises. There are several varieties of them, to protect the thermal insulation of the bath from steam, film isospan B is more suitable. It is also widely used:

• multilayer insulation attic space and attic and all types of sloping roofs;
• internal and frame walls;
• basement and interfloor ceilings.

The construction market also offers Izospan groups A, C, D and AM. Its varieties are used for complex insulation and protection against condensate in roof and wall structures. All varieties are characterized high level protection from the main factors with a negative impact on the building materials of the frame, roof and walls of the building. The foil surface is capable of reflecting up to 90% of thermal radiation into the room. This allows you to minimize heat loss when heating a house or heating a bath.

Fiberglass belongs to a group of high-tech materials that are widely used in construction and decoration (glass wallpaper for painting). It does not burn, protects surfaces from negative effects, bends well and folds into rolls, unlike glass. Due to its resistance to decomposition, it is often used in the steam room - it does not emit toxic substances when overheated.

Polyethylene film was used to waterproof the bath when there were no membranes of the latest generation. But it also prevents steam from penetrating into the thermal insulation layers. It does not tolerate temperature extremes, loses elasticity and collapses over time. It can be used only in this bath, which is rarely used and not very warm. It is important to fix it well on the crate with a stapler and seal the seams with heat-resistant tape. It is advisable to do between mineral insulation and a small gap with a film to give room for condensate flowing down.

Each variety has its own advantages and disadvantages. Outdated roll materials are more accessible, but they do not have the advantages that are inherent in the latest generation of multilayer membrane and foil insulation. For a country bath used occasionally in summer period, you can use the budget option.

In a sauna, steam room, bath, used all year round, with a high temperature load, a universal multi-layer vapor barrier with insulation is used. Do not forget about ventilation and the possibility of removing condensate from the insulation, if it forms there, so as not to get damp.
